To all whom it may concern:

Be it known that I, REINHOLD GRABEIN, of 9 Richtstrasse, Forst, inLusatia, in the German Empire, have invented anew and useful Improvementin Mechanism for Supplying Single Hairs to a Spinning-Machine, of whichthe following is a specification.

This invention relates to mechanism for conveying single hairs or thelike from a bundle for the purpose of producing a continuous thread andmore especially a horsehair-thread. In mechanism of this kind ithasheretofore been usual to draw the single hairs fromthe bundle and toconvey them to the feed rolls by means of reciprocating pincers, or byimparting a reciprocating movement to the receptacle containing thebundles of hair, the pincers remainingsta-. 'tionary. Such devices are,however, all subject to the defect that the reciprocating movement ofthe mechanism vibrations which renders it di cult to grip single hairswith certainty; and these vibrations, moreover, often result indisturbing the position of the hairs in the receptacle as well as theposition of the single hairs relatively to each other, with the resultthat the forward'movement f of the hairs may cease to be uniform. Forall these reasons it has'been impracticable, by means of any of the.mechanism heretofore devised to effect a uniform feed and consequentlyalso to produce a uniform thread. Moreover in all the mechanismheretofore proposed it is necessary to draw out the horsehair and tomove it forward to some extent, with the result that in all suchmechanism the distance betweenthe gripping device and the drawing-outdevice has had to be relatively large which again has rendered itimpracticable to use horsehair of less than a certain minimum length.

Now in mechanism in accordance with this invention these defects'areobviated by causing a uniformly rotating pair of pincers of the pincettetype to move tangentially past the bundle of horsehair and durlng suchmovement to grip a number of hairs, the precise quantity being capableof regulat-ion, to hold them, to move thenrforward and then again torelease them.- By means 'ves rise tov of this mechanism a uniform threadcan consequently be produced from very short hairs and even. from wastehairs which hitherto could not have been utilized. The quantity ofhorsehair taken up during each rotation can very easily be adjustedduring the operation. The steady working of the mechanism due to theabsence, of reciprocating parts enables the apparatus to be operated ataconsiderably increased speed with a corresponding increase in'theoutput.

The accompanying drawings illustrate mechanism in accordance with thisinvention; wherein I Figure l is a side elevation of the mechanism; Fig.2 is a vertical transverse section on the line 1141 of Fig. 1 and Fig. 3is a i plan View of the ripping mechanism.

Referring to. the drawings: a indicates the trough through which thebundle of horsehair is fed and which is provided at its lower portionwith a slot Z), through which the pincers 0 enter as they rotate uponthe shaft (1. The pincers are fixed as shown upon, the rotating disk ewhich is actuated by the cord-pulley f. The shaft (1 of'the diske issupported. by the bearing g to which there is attached a plate Itcarrying a face cam 1" that as the disk e rotates actuates the pincersc. For this purpose the disk e is furnished with a pint that projectsparallel to the shaft (1 and one end of which bears against the face ofthe cam 1* while its other end bears against the-"free arm of thepincers 0. During the rotation of the disk 6 the pin i is caused to movein the direction of its length and thereby to open the pincers. Theopening of the pair of pincers can be accelerated or retarded byadjusting the position of the plate 72. by rotating it on the rigidbearing g. -Adjustment is effected by means of the set screw 1 whichpasses through a flange p formed on the rigid bearing 9 andinto theplate It. A slot 8 is provided in said flange. p as shownin Fig. 3. Bycausing the pincers to open sooner or later the distance towhich theho-rsehairs are drawn out of the bundle of hair can be varied. In orderto determine with accuracy the quantity of hair to be drawn during eachrotation from the i bundle of hair the pincers are furnished at theirextremity with a small threaded pm is which bridges the gap between thetwo arms of the pincers when moved apart. This pin can be adjusted in aslot Z and by this means the quantity of hair taken up during onerotation can be varied as desired. The

- pincers are normally closedby means of a spring m their opening beingefiected only by the pressure of the pin in Durin the rotation of thedisk 6 and 'the pairo pincers the hairs are gripped, drawn out of thebundle of horsehair, and fed to the rollers 11. 0 whence they areconducted through a funnel to the spindle.

Having now particularly described and ascertained the nature of my saidinvention and in what-manner the same is to be per-.

formed, I declarethat what I claim is I g 1. In a'device of the classdescribed, in combination, a horizontallydisposed trough adapted to holdthe hair, said trough being fixe said trough being provided with a slotin its lower portion extending in the direction of its length, feedrolls, rotatable pincers positioned below said trough and adapted topass through said slot in the directlon of the length of the trough tograsp the hair and convey it from said trough to said feed rolls, meanscomprising a cam member for controlling the opening-andclosing movementof said pincers, said pincers being positioned tangentially with respectto the direction of rotation, and means to rotate said pincers.

3. In a device of the class described, in combination, a horizontallydisposed trough adapted to hold the hair, said trough being fixe saidtrough being provided with a slot in its lower portion extending in thedirec-' tion ofits length, feed rolls, rotatable pincers positionedbelow said trough and adapted to pass through said slot in the directionof the length of the trough to grasp the hair and convey it from saidtrough to said teed rolls, said pincers being positioned tangentiallywith respect to the direction of rotation, a reoiprocatable pin engagingone of the arms of said pincers, a spring normally holding the arms ofsaid pincers in closed position, means for reclprocating said pin duringthen-rotation of said pincers whereby they will be opened and closed,and means to rotate said pincers.
